Information Systems Research Laboratory ( ISML ) of Vilnius Gediminas Technical University carries out relevant research and practical work in field of computer engineering sciences. The researches are carried out across the spectrum of systems engineering, information systems engineering and software engineering problems. The aim is to determine the scope of such systems, needs, requirements, etc. Informatics engineering professionals performs different tasks: provides consultations, various expertises, prepares Government programs.The most important laboratory research fields are:

Intelligent Information Systems development methods and architecture of such systems

business, technical ( engineering ) information systems

rule-based business information systems.

In 1998, O. Vasilecas was elected as expert in field of Information and software systems in Lithuanian Computer Society. Team of ISML collaborates with European and other counterparts in joint research projects, organize international events. Information Systems Research Laboratory belong to Faculty of Fundamental Sciences.
